MIRON (ll. TOUSLEY, OF MENDOTA, ILLINOIS, ASSIGNOR TO DIEBOLD 85KIENZLE,

To all whom it may concern:

Be it kl iown that I, MIRON G. TonsLEv, of Mendota, i the county oir- LaSalle and State of Illinois, `ve invented a new and useful Improvemen inSafe-Lock Spindles, and I do hereby declar the following to be a full,clear, and exact des( 1iption thereof, which will enable others skilletin the art to which my invention appertains t make and use the same,reference being had o the accompanying drawing forming part oi' th sspeciiication, in which- Figure is a transverse longitudinal section ofa porti n oi1 the walls of a safe with my improvemen attached thereto,cutting the saine through t e center. Fig. 2 is a cross-section of thespind on line a' Fig. 3 is a detached section oi' y portion ofthe keyemployed in turning the s indle, and Fig. lis a vertical lengt tudinalse ion oi' a portion of the safe-walls, with dial remo d, showing themanner of closing the aperture ithin which the key for turning' thespindle is ntroduced.

Similar tters oi'rei'erence indicate corresponding parts the severalfigures of the drawing.

rIhe nat re oi my invention consists in so constructing 1e key inconnection with aloose plug' and the l Ak-spindle as to operate incombination, whe arranged as hereinafter described 5 also, in sarranging the inner portion of the spindle as o ignite a fuse securedtherein when force is ap lied upon its outer end to drive the same inwrld from the door, by which means an alarm is g 7en.

In the ccompanying drawing, A represents the dial, w rich may be made inthe usual form. B is the y, the shank of which is secured to said dial 1the ordinary manner. C is a steel plug, whic is secured within anannular cavity or apertur in the outer end of the spindle I). The outervnd of said plug is provided, at opposite sides, 'ith longitudinal slotsout obliquely across the nd, forming a wedge-shaped center. Into this st I introduce the blade d of the key for turnin the same, said bladebeing' cut away or fork-shaied, forming in its end a recess approximatisaid wedge-shaped center in the end of the pluU I provide said plug witha longitudinal groov or channel, within which is secured a feathery, I),that engages with and takes into a corr Vponding groove or channel uponthe inner side f spindle D, by which means said OF CINCINNATI, OHIO.

IMPROVEMENT IN SPINDLES FOR SAFE-LOCKS.

Specication forming part of Letters Patent No. 118,830, dated Septemberl2, 1871.

Thus, should a blow be applied to the outer end of the plug' (by meansof any instrument intro duced into the cavity for the key, when it isremoved) in the attempt to force the same inward, the cap is broughtagainst the solid end of the cavity in the spindle, exploding the same,which ignites the fuse, by which means an alarm is given and the plugdischarged from the spindle. I provide the inner side of the sate-wallwith an external screw-threaded disk, E, through which said spindlepasses. Said disk has in its end an annular cavity or recess, forming aseries of oblique and rectangular shoulders, h hf, which come in contactwith and against corresponding shoulders 17 i upon the spindle, by whichmeans the same is secured in the walls of the safe. Vhen the key withthe dial is removed from the spindle I introduce into the keyhole astopper, j, as shown in Fig. 4. Said stopper may be of cork or otherlike material, which will protect the fuse secured in the cavity of thespindle from the air or from ire. I at tach the shank of the spindle tothe lock in the ordinary manner; but, as the same forms no part of myinvention, a description thereof is not necessary to be herein fullygiven.

I am aware that spindles have been previously known and used which aresecured to the wall ofthe safe by a screw-threaded disk havingrectangular shoulders and of different general shape 5 but the rear ofthe shoulders is not properly secured, and their angles produce noexpansion to the disk, s0 the thread may be stripped and the spindledriven by the concussion oi' heavy blows, while with my invention theoblique shoulders of the spindle expand the disk by the concussion of ablow and are secured, rendering the same more strong and reliable.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination of key B with its forked The above speciiication ofmy invention signed end, loose plug,` C with Wedge-shaped end, and by methis 29th day of October, A. D. 1870. spindle D, substantially as hereindescribed. v MIRON G. TOUSLEY.

2. The plug C, provided with cap and fuse f A and g or theirequivalents, in combination with Witnesses: the spindle D, substantiallyas herein described, H. CADY, and for the purpose set forth. L. W.RICHARDSON.
